This is great news... Unfortunate as I used to be bullish on browser based push notifications, but in reality they were never working reliably on mobile devices.
I use a web API for my SMS gateway, and implemented push notifications via Firebase. It didn't matter whether I was using Fennec/Firefox, Chrome, or Vivaldi, I would always cease to be notified the moment the browser was killed off by my phone.
I eventually got sick of it and ported the logic over to call ntfy.sh instead. Not a single missed message since.
I've had no issue with Firebase on a personal project just pushing to my android. The big caveat is that the push doesn't wake the phone. So all notifications drop in when I click the screen on.
